NEURAL NETWORK INFERENCE WITHIN PHYSICAL DOMAIN VIA INVERSE DESIGN TOOL

摘要

A computer-implemented method for revising structural parameters of a physical device is provided. The method comprises configuring a simulated environment to be representative of the physical device based on an initial description that describes structural parameters of the physical device. The method further includes performing an operational simulation of the physical device based on training data representative of physical stimuli within a physical domain to simulate an interaction between the physical device and the physical stimuli. The method further includes computing a loss value based on a simulated output of the physical device and performing and adjoint simulation by backpropagating the loss value through the simulated environment. The method also includes generating a revised description of the physical device by updating the structural parameters to reduce the loss value.
